Warning
■Mounting cylindrical type
● Attach the mounting screw to the sensor
at minimum of 5mm away from the tip
of the sensor.
Be sure to keep the tightening torque
less than 0.4Nm when mounting.

■Mounting thread type
When mounting thread type sensor head,
tightening torque should be less than
specified below.

Influence of surrounding metallic
objects
● To flush mount the sensor that is
embedded in iron, provide enough
distance between the sensor and
surrounding iron as shown by the
following figure and table, because the
detecting distance is reduced by 10%.

Note: Consult Keyence regarding nonferrous materials.
■Mutual interference
When installing a number of proximity
sensors of the same model either face-to-
face or side-by-side, provide the minimum
distance given in the table between each
sensor.
Note :
Two types with different frequencies available.
(A) or (B) is written after each type name.

■Installing amplifier unit
A mounting bracket is
supplied as a standard
accessory. Use it to secure
the amplifier unit.
✽Do not use setscrews to
secure the amplifier unit.
Align the operation indicator of the
amplifier so that it positions at the center of
the mounting bracket hole as shown
below.

■Wiring
● To extend the cord, use an extension
cord with a conductor cross-sectional
area of 0.3mm
2
. Limit the length of the
extension to within 50m. Note that the
coaxial cord must not be extended or
cut.
● Ensure that the sensor cord is kept
away from power lines and high-
tension lines; otherwise, noise may
cause the sensor to malfunction.
The values enclosed in brackets are
when a different frequency type is used.
